Change ConfirmView to allow enabled/disabling of animation
Add confirm modal template to settings.py (this should have been done in #405 before it landed, sorry)
Align the '.dont-show' checkbox with its label
Change dialogue state edit views to use a ConfirmView (to make use of the 'dont send' thing it offers)
Unbind ConfirmView's events when '.ok' or '.cancel' is clicked instead of using once() (since that approach still allows the unclicked button's event to be bound)
Fix bad comment in DialogueStateModeView about resetModal event behaviour
Merge branch 'develop-frontend' into feature/issue-490-allow-users-to-disable-the-dialogue-state-reset-modal
